Concrete Foundation Wall/Shear Wall?
Concrete Foundation Wall/Shear Wall?
(OP)
I have been working on a foundation wall, and it has sparked some thought. I was designing a simple foundation for some equipment. The walls are continuous around the edge of the supporting slab. When designing the wall, there are the vertical gravity loads, self-weight, and lateral loads (in-plane) from wind/seismic.
My question is in the flexural steel in the shear wall. If the wall is a single wall, then there is a large amount of steel required on the ends of the wall. I am calculating this by hand, so I am wondering what the standard for design is in this case if I have a continuous wall that extends around each end of the wall. Is this the correct way to model the wall, and if so, how do I reduce the amount of steel required in the end of the wall (i.e. residential foundation only requires a single bar in corners and typical spacing otherwise)?
If not, what is the correct way to model a continuous foundation wall? Should I only be looking at the horiz/vert required steel for shear?

And the same applies to a slab rigidly connected to the walls, will act as a support the walls; all these effects are properly captured by a complete 3D model upon which the hypotheses are properly laid out.

I am looking at a 12'x40' pad for equipment that has a 5' deep continous wall around the exterior of the pad to support the equipment skid. The contractor wants to pour the pad and wall in a monolithic pour. So, I will have a thick wall to get my soil bearing area. I am trying to justify my requirement for horizontal and vertical reinforcement. I am almost certain that it will just be Asmin. However, I would like to have a complete set of calculations for this project.
